How to Install a Pulley on the 928 Snapper Mower

Use an adjustable wrench to help install a new pulley on a Snapper 928.

The Snapper 928 mower is part of the rear-engine riding mower series produced for homeowners with medium to larger-size yards. The 928 utilizes a belt and pulley system to transfer power from the engine to the spindles on which the blades are mounted. If a pulley, such as the idler pulley, fails, the blades will not turn and the mower is out of commission. Replacing the idler pulley will get you back up and running in a short amount of time.

1

Park the Snapper 928 on a level work surface such as a driveway or workshop floor. Locate the spark plug wire on the engine and pull the boot on the wire from the tip of the spark plug for safety. Put on gloves to protect your hands while working.

2

Lower the cutting deck to the lowest possible setting to allow room to access the belt and pulley. Loosen and remove the screws on both sides of the belt cover with a screwdriver. Set the screws aside in a safe location for use later. Pull the cover back and rotate it to remove it from beneath the mower frame.

3

Raise the 928 up by the front end and rest it upright on the rear bumper. Loosen and remove the idler belt guide with an adjustable wrench and pull the belt from around the idler pulley. Note the pattern that the belt follows around the top of the cutting deck through the spindle pulley, idler pulley and engine drive pulley.

4

Loosen the bolt that connects the idler pulley to the cutting deck with an adjustable wrench. Pull the bolt from the pulley and remove the pulley from the cutting deck. Obtain a suitable replacement idler pulley from a mower repair shop.

5

Set the replacement pulley on the cutting deck and secure it in place with the bolt that was removed. Tighten the bolt with the adjustable wrench.

6

Pull the belt over the new idler pulley and attach the idler belt guide back in place beside the idler pulley. Slide the belt cover back onto the deck and secure with the screws that were removed. Attach the spark plug wire back to the spark plug to operate the mower.
